Which word describes something that continues for a long time and is hard to stop?

• A. pedestrian
• B. pensive
• C. percent
• D. persistent

Answer: (D)

The idea is to recognize a word that signals ongoing action or presence over time and resistance to stopping. Persistent fits best because it describes something that continues for a long time and is hard to stop, implying steady, continued effort or persistence in the face of obstacles. You can use it for problems, efforts, or conditions that keep going.

Pedestrian refers to a person walking or, in a different sense, something dull or ordinary, which doesn’t convey duration. Pensive means thoughtful or reflective, not about how long something lasts. Percent is a number that denotes a proportion out of one hundred, unrelated to duration or stoppage.
